Purpose: This study aimed to assess the quality of sleep among medical undergraduates from different phases of the medical program using the Pittsburgh Sleep Quality Index (PSQI) and to study the association of body mass index (BMI) with the quality of sleep among them. Material and Methods: Sleep quality was assessed among 482 medical undergraduates using the PSQI. Students undergoing treatment for psychiatric illness, diabetes or hypertension, history of alcohol consumption, and smoking were excluded from the study. Obesity was ascertained by calculating the BMI and categorized into 2 groups of23.0 according to the World Health Organization (WHO) guidelines for the Asian population. The chi-square test was utilized to compare seven components of PSQI and sleep quality for different phases and BMI groups and SPSS 24 was used to compare the components and the global score. Results: Only 0.8% of the total sample classified their sleep as very bad whereas 69.5% classified themselves as fairly good sleepers. The study participants had an average sleep time of 7.06±1.26 hours. The sleep duration (p23 had daytime dysfunction every day. Conclusions: It is necessary to create awareness among medical undergraduates about the importance of good sleep hygiene which will help them to improve their academic performance.
